GAS-GENERATOR. Y f

SPECIFICATION forming part of Letters Patent No. 377,793, dated February 14, 1888.

Application filed May20, 1887. Serial No. 238,905. (No model.)

To all whom it may concern.-

`Be it known that l, AUGUsT WEYER, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented a new and useful Gas-Generator; and I' do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and' use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to gas-generators, and has especial reference to the class of gas-generators that are used for generating gas from resinous substances. In generators of this class as heretofore constructed it has usually been customary to charge a considerable quantity of resin at one time, necessitating the opening of the generator each time, which renders it impossible to make the operation continuous. The continuous feeding of heated resin through a small aperture has been attempted; but the flow of resin is unreliable, inasmuch as the aperture through which it ows will soon become clogged with foreign substances. Itis to obviate these difficulties that I have supplied this device, which consists of a generator and means of heating it,

vand a resin-tank and means of feeding from it device, one ofthe pipes by means of which the gas is conducted away, and the plug by means of lwhich the essential oil is drawn off. The arrangement of the iiues and dampers by which the heat of the generating-cylinders and the resin-tanks is regulated is also shown in this figure by the breaking away of a pipe and a portion of the furnacelwall. Fig. 2 is a central vertical section through a resin tank,v

showing the device by which the resin is fed into the generating-cylinder. Fig. 3 is a plan showing the inside of a resin-tauk.

In the figures, like reference-marksindicating corresponding partsin the several views, A isa brick furnace, of which a are the grates, and a is the chimney.

B are the generating-cylinders.

O are the resin-tanks, that are connected at the top to the generator B by the pipes c, and may be made integrally with the generator, but are preferably made separately and attached as shown in Figs.- l and 2. The hole D through -the pipe c, ora portion of it, as shown in Fig. 2, is made somewhat larger than would beV required tocarry in a steady stream the quantity of resin that would supply the generator. enough to fill up and entirely stop the hole D, but is tapered at its lower end nearly orquite to a point.` ln Fig. 3 is shown a wire-cloth covering for this hole, and also the part F, having in its center a hole through which the rod passes, and by which it is guided and steadied.

The working-beam-G, pivoted at the center and extending over the resin-tanks, is pivoted to the top ends of the rods E. In operating this device this lever is given a vertically-oscillating movement, usually by a pitman, g, attached to one extended end of the lever; but the rods F may be given a reciprocating motion, either alternately or at the same time,

by any other means without a departure from the spirit of this invention.

The resin-tanks C being su pplied with resin and being heated to the point of melting the resin, and the generating-cylinders B being partially lled with coke or other suitable substance and heated to the point of generating the gas, the gas will pass off through'the pipes H, and such of its essentialv oil as may be deposited in these pipes can be drawn by valves J. It is obvious that the reciprocation of the pointed rods F, Fig. 2, will alternately open and close an aperture, which is suflicient, when opened, to allow the melted resin to pass from the tank to the generator, and that by closing will prevent the accumulation of foreign substances in the opening that might otherwise stop it up and prevent or serious] y restrict the flow. For this purpose the rod E may be lifted at'each stroke, according to the condition of the resinous substance used, entirely The body of the rod E is large IOO out of the hole, which would cause it in returning to force through the hole and into the generator some of the obstructing substances, or only be lifted sufficiently to leave, by reason of its tapering shape, a sulcient opening around it for the discharge of the required quantity of resin. The wire-cloth shown in Fig. 3 is placed over the greater part of the opening D to obstruct the passage of any substances of a considerable size. The rod F therefore Will permit a uniform quantity of resin to flow to the generator at each stroke, the quantity being regulated by the length and frequency of the stroke and the temperature of the resin. 'Ihe length of the stroke and its frequency maybe regulated in any manner, as may also the temperature o' the resin; but I prefer to regulate the temperature, as will be hereinafter described.

I have shown and described two ofthe generators and tanks; but, both sets being alike, all the elements of my invention are contained in each set, so far as the invention relates to them; but I believe it to be preferable to construct them in pairs on account of the greater convenience in operating them.

The construction of one ofthe furnaces, both being alike, is as follows: Under the generators B and within the `walls A is the fire box K. A chamber is also formed around the bottom part of each resin-tank by the vertical partition-wall L and the horizontal partitionwalls M. The wall. L has through it the flue l from the lire-box, which fine extends around a portion of the length of the generating-cylinder and leads to the chimney a. The damper Z is provided for the purpose of closing this ue. Flues m pass from the fire-box to the chamber surrounding the resin-tanks, and are provided with the dampers m.

It is important that the heat of the fire-box should be sufficient to generate gas in the cylinders B, and the heat required for that purpose is a uniform quantity; but the quantity for heating the resin-tank varies accordingly as the condition and quantity of the resin. For the purpose of diverting to the heating of the tank such a portion of the heat as may in its passage from the fire-box to the chimney be required for this object, I have devised the lcontact with the resin-tanks.

arrangement of the fiues and dampers above described, and I will now describe the operation of the heating apparatus as shown and applied to the generators and tanks.

In heating the generators to the degree that will decompose the resin it is preferable to close the dampers m' and open the damper Z', to open communication from the fire to the chimney without allowing the heat to come in The damper l', however, should be closed and the dampers m opened a suicient length of time before the generation of gas is to be commenced,to allow the resin in the tanks to be liquefied by the heat in passing in their direction to the chimney, after which the dampers should bc adjusted to admit exactly the required amount of heat to the chamber around the resin-tanks and the draft required in addition to that be carried through the flue l and damper l.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a gasgenerating apparatus, the com* bination of the retorts B and resin-supply tanks C, each tank having Van outlet through the opening F and connected to said retorts bythe pipes c, the needle shaped rods E, attached to an oscillating lever, and means for operating the same, whereby a continuous iiow of resin from the tank to the retort is effected, substantially as set forth. Y

2. In a gas-generating apparatus, thc combination, with the retorts B B, provided with the resin-supply tanks G C, placed directly over said retorts,of a furnace consisting of the fire-box, the vertical partitioirwalls and horizontal partition walls forming a chamber around the lower part of the resin-tank, said walls having dues Zand m, respectively, and the latter provided with dampers l and on', whereby a uniform heat may be maintained about the retort and supply-tanks, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

AUG. WEYER.
